What are the 4 main causes of climate change?

Causes for rising emissions

  • Burning coal, oil and gas produces carbon dioxide and nitrous oxide.
  • Cutting down forests (deforestation). …
  • Increasing livestock farming. …
  • Fertilisers containing nitrogen produce nitrous oxide emissions.
  • Fluorinated gases are emitted from equipment and products that use these gases.

What percent of climate change is natural?

Less than 1% of the research papers they reviewed rejected the idea of human influence on our climate. And while 66.4% of the abstracts expressed no position on the anthropogenic factor, 32.6% endorsed it. Further analysis of the latter figure revealed a 97.1% consensus on human-caused climate change.
